Be it known that I, MORRIS P. PARKINSON, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented a new and useful Artificial-Light Reflector for taking all kinds of photographs at night or atany other time withoutthe use of daylight, of which the following is a specification.

My invention relates to an improvement in a machine for reflecting artificial light for all kinds of photographing, and the object of my improvement is to do all kinds of photographing by artificial light. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a central vertical section of the entire machine; Fig. 2, a plan view showing the screen B part of the reflector A open; Fig. 3, a side View; Fig. 4, a side View of a spring with pulley attached, and Fig. 5 an end view of the spring with pulley attached.

Similar letters refer to similar parts throughout the several views.

The reflector A is nearly of the shape of a hemisphere, and has for its outside covering any material which can be suitably fastened to the ribs D D, a light cloth or canvas being preferable, and having for its inside, which is hollow, a lining of any material best adapted to a gentle reflection of light, papier-mach or cloth being the most preferable, the color being white.

Attached to the periphery of the reflector A by the means hereinafter described is an adjustable screen B, the outside and inside covering being made of the same material as the reflector A. This adjustable screenB, which is attached to and forms a part of the reflector A, is used for concentrating and throwing the light (reflected by the reflector A) upon the object to be photographed at any point desired.

The point or place upon which the light is thrown is governed by raising or lowering the reflector with the rope or cord I,the rope or cord I being attached to the eye H and passing over through the eye j, and passes over the pulleys M M, and also by shifting the vertical stand G,

which is set upon casters, or by raising orlowends of the ribs D D to hold them in place,

then through the curved piece of metal E, and, lastly, through the metal plate H and secured by a nut. 1

The amount oflight reflected or thrown upon any point or place (which may be the object to be photographed) is governed by opening or closing the adjustable screen part of the reflector B. It may be opened/to'a" width which the dotted line B indicates, thus reflecting the light upon a larger space, or it may be closed, as shown in Fig. 1, thus reflecting the light upon a smaller space, or it may be opened or closed to any space desired, or assume any shape desired within the largest or smallest space.

The adjustable screen B part of the re- Hector A is opened or closed by springs O 0,

being fastened to the ribs D D, as shown by a in Fig. 3, and also being fastened to the outside covering and having upon the ends 85 of the springs O 0 small pulleys b b, as shown in Figs. l and 5, over which the cord or wire d passes, the cord or wire d also passing through the reel 6. (Shown in Fig. 2.) By

winding or unwinding the reel 8 the cord or wire cl is tightened 0r loosened and opens or closes the adjustable screen part of the refiector. Although the adjustable screen B part of the reflectorA may be opened or closed,

as heretofore described, yet I do not limit my- 9 5 self to this method of doing so, as a cord may be fastened to each end of the springs O C for throwing them in toward the center, and fastened together in the center of the circle of the adjustable screen B in such a manner as not to interfere with the light.

Around the peripheryof the reflector A at the place where the springs G G are fastened to the ribs D D is a band g, which is used 7 may be used in connection therewith.

for strengthening the reflector A and for holdband g and about in line with the periphery and about in the center of the circle. The continuous light most preferable and more nearly like natural light is an are electric lamp, and the light from the lamp is prevented from reaching the object to be photographed directly by using a solid and unperforated concavo-convex piece of metal, the concave side, which is nearest the light, being dull and non-reflective. Although any other shaped piece of metal may be used to prevent the light from reaching the object to be photographed directly, it is necessary that it should be unperforated and that the side nearest the light should be dull and unpolished, in order that the light may strike the inside reflecting-surface of the reflector A softly and then be reflected toward theobject to be photographed without producing a glare.

The reflector A and the adjustable screen B, which is attached to and forms a part of the reflector A, may be made of any dimensions desired and one or more artificial lights The probable size is about seven feet in diameter when open or about three feet when drawn in at the opening.

ing of light materialsuch as cloth or papierlllft'Ch-?L'tt&0lld to the outside of the curved ribs D D, and a suitable lining of White material, preferably white cloth or papier-mach, attached to the inside of the curved ribs D D, all as heretofore described.

2. In an artificial-light reflector, the combination of the following parts: the adj ustable screen B, attached to and forming a part of a reflector A, the springs C O, the pulleys b b, the cordYl, and the reel 6, and a suitable covering of light materialsuch as cloth or papier-ma'ch-attached to the outside of the springs C O, and a suitable lining of white material, preferably white cloth or papier mach, attached to the inside of the springs O 0, all as heretofore described.
